Get the solution ↓↓↓

Solution:

As display in first script, you are not getting any result of index: id, and you have passed parameter in URL. Now in second script you are using id as get parameter. But as you know you don't have any index named id, you can't get id from URL, and when you are trying to run the query there's a query error and it returns non-object.

replace following line:

<a href='answ.php?id = " . $row['id'] . "'><?php echo $row["question"]; ?> </a>
Copy code

with:

<a href='answ.php?id=<?php echo $row['id']; ?>'><?php echo $row["question"]; ?> </a>
Copy code
